Tom Burdick	97dc88bb6d	tracing: Automatic syscall tracing When generating syscall wrappers, call a tracing macro with the id, name, and all parameters of the syscall as params when entering and leaving the syscall. This can be disabled in certain call sites by defining DISABLE_SYSCALL_TRACING which is useful for certain tracing implementations which require syscalls themselves to work. Notably some syscalls cannot be automatically traced this way and headers where exclusions are set are in the gen_syscall.py as notracing. Includes a systemview and test format implementation. Tested with systemview, usb, and uart backends with the string formatter using the tracing sample app. Debugging the trace wrapper can be aided by setting the TRACE_DIAGNOSTIC env var and rebuilding from scratch, a warning is issued for every instance a syscall is traced. Automatically generating a name mapping for SYSVIEW_Zephyr.txt is a future item as is documenting how to capture and use the tracing data generated.

Anas Nashif	41abcc57c1	tracing: move tracing under subsys/ Tracing subsystem is growing and although related to debugging, it does deserve to belong into its own subsystem. Signed-off-by: Anas Nashif <anas.nashif@intel.com>	5 years ago
Wentong Wu	8ccc04de6a	tracing: add infrastructure for collection of tracing data First, this commit adds user interface in tracing_format.h which can trace both string format and data format packet. Second, it adds method both for asynchronous and synchronous way. For asynchronous method, tracing packet will be buffered in tracing buffer first, tracing thread will output the stream data with the help of tracing backend when tracing thread get scheduled. Third, it adds UART and USB tracing backend for asynchronous tracing method, and adds POSIX tracing backend for synchronous tracing way. Also it can receive command from host to dynamically enable and disable tracing to have host capture tracing data conveniently. Signed-off-by: Wentong Wu <wentong.wu@intel.com>	6 years ago
